Reliability of the DPE: the responsibility is also to be sought on the side of the software!

“Any action involving humans is, by definition, subject to interpretation and therefore to chance. The real question, however, is the depth of these differences and their impacts. commented F. Annamayer, recalling that the DPE is now a well-known tool for French people, serving as a reference for locating their housing in terms of energy and carbon performance.

For several months, Sonergia has chosen to investigate this subject of the initial state of housing, the keystone of energy renovation work partly financed by CEE premiums. With this in mind, Sonergia announced, in June 2021, its acquisition of a stake in the capital of Homeys, a start-up whose foundation is to democratize the analysis of housing data through artificial intelligence. “The results of the UFC Que Choisir survey are worrying, especially since the DPEs are now enforceable! In the age of open source, high-performance tools must make it possible to improve the quality of the DPEs produced and to minimize the place given to judgement” according to Franck Annamayer who, rather than incriminating a profession, opens avenues for progress.

Training is of course important and the associated skills cannot be ruled out to ensure good reliability. But the diagnostic tool and its good grip are at least as good. For Sonergia, the solution therefore lies in the joint phygital approach. In concrete terms, it consists of collecting as much open source data as possible upstream, then having a professional visit the accommodation to confirm and refine the first elements collected. “We are working on this approach with thermal engineers, the CSTB and our historic partner SOLIHA. The wish is to provide a robust tool in the coming months that will overcome all the pitfalls identified by the UFC Que Choisir and can also push the analysis by proposing an energy audit if necessary. informs the president of Sonergia.

To be continued very soon, therefore…
